Key information relevant to the recruitment process for the
overall study, such as dates of the recruitment period and locations

Male or female untreated participants, who were at least 18 years of age, with metastatic and/or unresectable, measurable predominantly clear cell renal cell cancer (RCC) histologically or cytologically documented could participate in this study at 18 centers in 6 countries.

Description

Regorafenib (Stivarga, BAY73-4506)

Participants received Regorafenib 160 mg per os (po) every day (qd) for 3 weeks on 1 week off of every 4 week cycle

The ECOG PS ranged from Grades 0 to 5 (death). Grade 0 (fully active, able to carry on all pre-diseases performance without restriction) and Grade 1 (restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature) were inclusion criteria.

The Motzer score (high/poor risk, intermediate risk, low risk) is based on the number of the following poor prognostic features a participant possessed: ECOG >2, serum lactate dehydrogenase concentration > 1.5 times the upper limit of normal, hemoglobin < lower limit of normal, corrected calcium concentration > 10 mg/dl, and absence of prior nephrectomy. Participants who had none of these features = low risk; participants with 1 or 2 of these features = intermediate risk; participants with 3 or more of these features = high/poor risk and were excluded from participating in the study.

Objective Tumor Response [ Time Frame: From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009). Assessed every 8 weeks for 6 months, then every 12 weeks ]

Tumor Response [ Time Frame: From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009). Assessed every 8 weeks for 6 months, then every 12 weeks ]

Disease Control [ Time Frame: From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009). Assessed every 8 weeks for 6 months, then every 12 weeks ]

Progression-free Survival (PFS) [ Time Frame: From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009). Assessed every 8 weeks for 6 months, then every 12 weeks ]

Time to Progression (TTP) [ Time Frame: From start of treatment of the first participant until database cut-off approximately 13 months later (13May2008 - 31May2009). Assessed every 8 weeks for 6 months, then every 12 weeks ]

TTP was calculated as time from first date of receiving study drug until date of first documented disease progression (PD) (radiological or clinical, whichever was earlier). The actual date of tumor assessments (i.e., date on which radiological procedure was performed, rather than the scheduled date) was used for this calculation to determine both the event date and censoring date. Patients without PD at time of analysis were censored at last date of tumor evaluation.
